The Electric Lexus LFA Could Get A Fake Sequential Gearbox

Toyota has filed a patent application describing a way to fake a manual transmission in an electric car. The timing lines up with the all-electric Lexus LFA, which is expected to arrive in 2027.

The system uses torque control instead of a clutch. It could end up connected the LFA Concept's steering wheel paddles.

The application, first reported by CarBuzz, lays out how an EV can mimic the jolt of a sequential racing gearbox without any clutch pedal at all. Lexus has not confirmed the tech is headed for production.

The patent application outlines a system that shapes electric motor torque over a set period to recreate the feel of changing gears, even though an EV has no gears to change. Instead of a conventional transmission, software manages how power reaches the wheels and when.

Toyota's filing explains the thinking plainly: operating a clutch can be troublesome for drivers accustomed to automatics, and most EV buyers will probably have had little to no experience with a real manual.

That line reflects earlier ideas. Prior patent work referenced a simulated manual with a pseudo clutch pedal, and it flagged that layout as potentially inconvenient for drivers who had never used one.

Dropping the pedal also has a performance upside. The patent notes that cutting the clutch out of the equation allows for quicker shifts. It more closely replicates how a real sequential gearbox behaves on track.

The mechanism itself centers on a temporary torque cut. During a simulated shift, the system drops motor torque to zero, then restores it. Sometimes it briefly overshoots the target figure to imitate the snap of a clutch re-engaging under load.

Drivers would reportedly get selectable profiles, including sport or race modes, that change how aggressive those torque cuts feel. A race setting could sharpen the simulated shift bite, while a milder mode might smooth it out for daily driving.

Hyundai already sells something similar. The Ioniq 5 N's N e-shift feature uses comparable torque manipulation paired with paddle shifters, and Porsche has filed patents covering related territory. Toyota is not chasing an unproven concept.

Lexus has already shown steering-wheel paddles on the LFA Concept unveiled in 2025, first as the Lexus Sport Concept at Monterey Car Week and the Japan Mobility Show. That concept recently appeared in Australia for the Melbourne Cup Carnival, still without official power, battery, or range figures attached.
